From my Google search, I'm not alone with this issue. Machine automatically updated to 14.04, now it will not access the internet. I'm not very conversant with Linux, but I have verified I can ping the following:
192.168.1.1 (default route)
But I cannot ping an address, like www.Google.com
. When I do, I get
unknown host google.com
The info under Active Network Connections looks normal.
